You asked: Which of the following events does not take place during prophase in mitosis?

Which of the following events does not occur during prophase of mitosis? The mitotic spindle breaks down. Which event or events occur during anaphase?

What events occur during prophase of mitosis?

The first and longest phase of mitosis is prophase (Figure below). During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell.

Which of the following events does not occur in prophase of mitosis but does occur in prophase of meiosis?

The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Which of the following events occur during prophase?

The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the beginning of nucleoli break down.

Which of the following does not occur during mitosis?

Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes.

What happens in prophase and prometaphase?

When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.
